Peretinoin reduces the mRNA level of sphingosine kinase 1 (SPHK1) in vitro by downregulating a transcription factor, Sp1. Peretinoin prevents the progression of non-alcoholic steatohepatitis (NASH) and the development of hepatocellular carcinoma (HCC) through activating the autophagy pathway by increased Atg16L1 expression. Peretinoin inhibits HCV RNA amplification and virus release by altering lipid metabolism with a EC₅₀ of 9 μM.

Liarozole (R75251; R85246) is an imidazole derivative and orally active retinoic acid (RA) metabolism-blocking agent (RAMBA). Liarozole inhibits the cytochrome P450 (CYP26)-dependent 4-hydroxylation of retinoic acid (IC₅₀=7 μM), resulting in increased tissue levels of retinoic acid. Liarozole shows antitumoral properties.

Tarenflurbil ((R)-Flurbiprofen) is the R-enantiomer of the racemate NSAID Flurbiprofen, Tarenflurbil ((R)-Flurbiprofen) inhibits the binding of [³H]9-cis-RA to RXRα LBD with IC₅₀ of 75 μM. Tarenflurbil can be used for Alzheimer's disease research.

Bigelovin, a sesquiterpene lactone isolated from Inula hupehensis, is a selective retinoid X receptor α agonist. Bigelovin suppresses tumor growth through inducing apoptosis and autophagy via the inhibition of mTOR pathway regulated by ROS generation.

Halcinonide (SQ-18566) is an orally active Smoothened (Smo) agonist. Halcinonide activates the Hedgehog signaling pathway by binding to Smo and promoting its internalization and expression, thereby activating Gli transcription factors. Halcinonide not only stimulates cell proliferation, increases the expression of cyclin D2/CDK6 and inhibits the degradation of caspase-3, but also suppresses Bcl-2/Bax-mediated apoptosis, oxidative stress and inflammatory responses. Halcinonide activates RxRγ to upregulate the expression of myelin genes, thereby reducing cerebral infarction and improving behavioral deficits. Halcinonide has been used in studies related to multiple sclerosis and ischemic stroke.

(+)-Talarozole is a potent inhibitor of retinoic acid metabolism extracted from patent WO 1997049704 A1.

Amsilarotene (TAC-101; Am 555S), an orally active synthetic retinoid, has selective affinity for retinoic acid receptor α (RAR-α) binding with K_i of 2.4, 400 nM for RAR-α and RAR-β. Amsilarotene induces the apoptotic of human gastric cancer, hepatocellular carcinoma and ovarian carcinoma cells. Amsilarotene can be used for the research of cancer.

PROTAC RAR degrader-1 (Compound 9) is a potent and selective RAR PROTAC Degrader consisting of apoptotic protein inhibitors (IAPs) ligands. IAPs-based degraders are also known as SNIPERs. PROTAC RAR Degrader-1 reduces RARα levels in HT1080 cells in a concentration-dependent manner but is blocked by the proteasome inhibitor MG132 (HY-13259). PROTAC RAR Degrader-1 can be used in the study of nuclear receptor-related diseases. (Pink: RAR ligand 1 (HY-111843); Black: Linker (HY-140189); Blue: IAPs Ligand (HY-B0134)).

Liarozole (R75251) dihydrochloride is an imidazole derivative and orally active retinoic acid (RA) metabolism-blocking agent (RAMBA). Liarozole dihydrochloride inhibits the cytochrome P450 (CYP26)-dependent 4-hydroxylation of RA (IC₅₀=7 μM), resulting in increased tissue levels of RA. Liarozole dihydrochloride shows antitumoral properties.

RXR antagonist 5 (compound 22) is a selective retinoic acid X receptor (RXR) antagonist with binding potential to RXR evaluated by modeling.

(-)-Talarozole is a potent inhibitor of retinoic acid metabolism extracted from patent WO 1997049704 A1.

Talarozole (Standard) is the analytical standard of Talarozole. This product is intended for research and analytical applications. Talarozole (R115866) is an oral systemic all-trans retinoic acid metabolism blocking agent (RAMBA) which increases intracellular levels of endogenous all-trans retinoic acid (RA). Talarozole inhibits both CYP26A1 and CYP26B1 with IC50s of 5.4 and 0.46 nM, respectively.
